About 3-4% of all pregnant women will have a fetus presenting by the breech at term. External cephalic version offers the opportunity to reduce the rate of caesarean sections caused by breech presentation. We analysed retrospectively 51 cases of external cephalic version at our clinic.
External cephalic version was performed 51 times between 37 and 41 weeks of pregnancy.
External cephalic version was successful in 32/51 cases (62,7%) with a consecutive rate of vaginal delivery of 71,9%. The best results were seen at 37 weeks of pregnancy with 81,25% of successful versions followed by 76,9% of vaginal deliveries. Complications were rare. There was just 1 case of emergency caesarean section due to persisting fetal bradycardia.
External cephalic version is an effective and safe treatment to enable vaginal delivery of cephalic presentation. For this operation, 37 weeks of pregnancy can be considered the best time.
所有孕妇中约有3%-4%的胎儿在足月时为臀位。外倒转术为降低臀位分娩导致的剖宫产率提供了机会。我们回顾性分析了我院51例外倒转术病例。
在妊娠37至41周期间进行了51次外倒转术。
51例中有32例（62.7%）外倒转术成功，阴道分娩的连续成功率为71.9%。妊娠37周时效果最佳，外倒转术成功率为81.25%，随后阴道分娩率为76.9%。并发症罕见。仅1例因胎儿持续性心动过缓而行急诊剖宫产。
外倒转术是一种有效且安全的使头位胎儿经阴道分娩的治疗方法。对于该手术，妊娠37周可被视为最佳时机。
